well sometimes when i play any map i get a problem whit graphics.there's the images.(how you see i get a black graphics everywhere and i can see behind the all walls, yes i can see the enemie comming behind walls if i look to the bug direction)

but it's only when i look to one way of the map. for example if i look to est then i see the "bad graphic" but when i look to north/west/sud the graphics are fine.,also no matter where i am on the map. always i look to the bug direction y saw the bad graphics.

that bug graphics don't happend me always. but when happend it's until the map finish.
